What must personnel do when operational parameters are not met during ATM operations?

When operational parameters are not met during Automated Test Management (ATM) operations, the appropriate course of action is to shut down the system. This step is critical because continuing to operate the system while it is not functioning within the specified parameters can lead to equipment damage or catastrophic failures. Shutting down the system allows personnel to prevent further issues and ensure safety.

In this context, it is essential to prioritize safety and the integrity of the equipment. Operating outside of designated parameters may compromise performance, lead to inaccurate results, or pose risks to personnel and equipment. Thus, shutting down the system serves as a protective measure that enables a thorough evaluation of the situation. Following shutdown procedures, personnel can then assess the root cause of the parameter discrepancies and determine the necessary steps for rectification, which may include contacting technical support or conducting repairs, but those actions come after a safe shutdown.
